The invention discloses a high-speed railway vehicle bogie which is arranged in an inner axle box mode, a hinged framework is supported on the inner side of a wheel set and can improve the curve passing performance of the bogie, a side beam is provided with a downward concave section, and a hinged cross beam is connected to the downward concave section through a flange. Free rotation between the two side beams can be achieved through the hinged cross beam, that is, the torsional rigidity of the bogie is zero, the uniform load energy, the line adaptability, the curve trafficability and the operation stability of the bogie are enhanced, the operation speed of a vehicle is increased, the contradiction between the high-speed operation stability and the curve trafficability of a traditional bogie is fundamentally solved. The installed anti-side-rolling torsion bar does not influence the free nodding movement of the two side beams, so that the bogie has good anti-side-rolling performance atthe same time; by the adoption of the primary suspension, the positioning rigidity of the primary suspension in all directions can be determined by independent components and can be optimal at the same time, and primary suspension parameters are more accurate and reliable.

    本发明公开了一种高速铁道车辆转向架,采用内轴箱方式布置,所述铰接构架支撑在所述轮对内侧,能改善转向架的曲线通过性能,所述侧梁具有下凹段,所述铰接横梁通过法兰连接于所述下凹段,使用所述铰接横梁能实现所述两侧梁间的自由回转,即转向架的扭转刚度为零,增强了转向架的均载能、线路适应能力、曲线通过性和运行稳定性,提高车辆的运行速度,从根本上解决了传统转向架高速运行稳定性和曲线通过性之间的矛盾,安装的抗侧滚扭杆不影响两个侧梁进行自由的点头运动,使转向架同时拥有良好的抗侧滚性能;采用所述一系悬挂能使一系悬挂各个方向的定位刚度都由独立的部件确定并能同时达到最优,使一系悬挂参数更加准确可靠。
